RHODE ISLAND, ASSIGNUR TO PRICE-CAMPBELL COTTON PICKER CCRPORATION, OF NEW YORK, N. 1 A CORPORA- TION OF DELAWARE.

BAFFLE-PLATE Application filed April 30, 1913.

To all whom it may concern."

Be it known that I, BENJAMIN CRABTRE'E CALnnRwooD, a citizen of the United States, residing at Valley Falls, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Bathe-Plates, of which the following is a specification.

My invention relates to improvements in battle plates for cotton cleaners on cottonpicking machines whereby the baflie plate is so formed that it assumes the shape of an irregular triangle, one side ofwhich is in the form of an arc of a circle, while the other forms an incline when placed in the cleaners down which the cotton dolfed from the first of the two sections in the cleaners is directed onto the conveyer belt in the rear section, where a similar process of cleaning is gone through before the cotton is deposited into the proper receptacles. The cleaning processes and the functions of the baffle plate will be explained in a subsequent paragraph.

The are of the. baffle plate has a radius slightly larger than the card roller, and when in position the centers of both radii occur at the same point. The result is a com paratively small open adjustable space between the periphery of the card roller and the arc of the baffle plate, which has the following effect.

In the event of any seed cotton not being removed from the card roller by the combined fan and dofler, which will be de scribed in a later paragraph, the cotton will be carried between the baffle plate and the card clothing of the card roller, the adjustable space previously mentioned will force the cotton onto the card clothing so that it will be carried back into the first section of the cleaners, and later doffed by aforesaid combined fan and doffer when it attains a certain point in relation to said combined fan and doffen The objects of my invention are: first, to provide means for depositing the seed cotton on the conveyor belt in the second or rear section of the cleaners after this has been treated in the first or forward section; and second, to provide against loss of the Specification of Letters Patent.

Serial No. 764,526.

, deposited on the first or forward conveyor belt 5, where it is opened and distributed evenly upon the surface of said conveyer belt 5, by the action of a breaker fan, not shown. From said conveyor belt 5 the cotton is next picked up by the action of the card roller 6. The cotton, adhering to the card roller, is carried on the periphery of this until at a predetermined point it is removed by the action of the combined fan and doiier 7, this fan and doifer also creating a strong current of air which blows dirt, sand, debris and foreign matter from out the cleaners.

The cotton, once removed from the card roller, is directed on the second or rear conveyer belt 8, which travels in the rear or last section of the cleaner, by the incline on the baffle plate 9 attached to the cleaner in the open space between the two conveyer belts 5 and 8. In the event of any seed cotton not being properly doffed it will be carried into the space 10 between the periphery of the card roller and the arc in the baffle plate, where it will be forced onto the card clothing and thus be brought back into the forward section of the cleaners and again be carried around by the card roller into the proper position for dofling.

The rear or last section of the cleaner, shown at 4, contains a mechanism similar in every detail to that contained in the first or forward section 3, thereby eliminating the necessity of describing the cleaning process a second time. Sufficient to state that the bulk of the cleaning is done in the forward section, which causes the rear section to as IOU sume the function of a refining or finishing process.

The cotton after cleaning, is deposited in the proper receptacles or containers through the outlet 11. 12 is a holder for the baffleplate 9, said holder in turn being attached to the cleaner bracket 13.

As will be seen from the arrows, the card roller rotates in a vertical plane, but in a direction opposite to that of the combined fan-anddofier, said fan-and-dofler rotating at a far higher velocity than the card roller. Also it will be seen that the conveyor belts travel in a direction which will carry the cotton from forward to rear.

In case any seed cotton is retained by the card and is not dofled by the dolfer 7, the member 9 operates to press this cotton into the card more firmly in order that it may be doifed on its next trip around with the card, but such compression doesnot constitute such an entanglement of the cotton in the card as to render the action of-the doffer 7 in any way insuflicient for practical dotting. It will be seen that the member or bathe-plate 9 which extends transversely across the machine, is held by one edge only. It is made of sheet metal and is therefore resilient. One of its inclined sides acts as an elastic presser, while the other extending toward the upper run of the belt 8 acts as a kind of chute.

\Vhat I claim is:

The combination of a card roller, a fan dotfer, and an endless receiving belt, with a transverse baffle plate approximately triangular in'cross-section, one side being arce'd and elastic and held adjacent the periphery of the card roller, and the other side being below the fan doifer and extending toward said belt, the free ends of the card teeth and the opposed surface of the baffle plate being slightly spaced apart, and the bafiie plate serving to keep the cotton from falling from the card roller if any fails to be doffed from the card roller by the fan dofier; the fan doifer being above the baflie plate and the .baflie plate being located in front of the card roller with its main portion below the axis thereof.

In testimony whereof I have hereun'to'set my hand in the presence of two subscribing witnesses, this 25th day of April, 1913.
